The Motor Effect
Preguntas del test (5)
1What is the motor effect?
- AWhen a current-carrying wire is placed between magnetic poles and the magnet and wire exert a force onto each other. This causes the wire to move.
- BThe induction of potential difference in a wire which is moving relative to a magnetic field.
2You can change the speed of the motor by changing the current?
- AVerdadero
- BFalso
3What is the name of the rectangular coil used in a motor?
- AArm
- BCommutator
- CArmature
- DSpring
4How can you increase the turning effect?
- AIncrease the current
- Bincrease the temperature
- Cuse a stronger magnet
- Dmove it further from the magnet
- Eensure that the wire is perpendicular to the magnetic field
5Force= magnetic flux density x current x length
- AVerdadero
- BFalso
